Steps To Perform Bathymetric Surveys What is Bathymetric Survey? Bathymetric is the study of the floor of a waterbody, which includes mapping of features on charts to offer details on water depth. These charts are usually made to help navigation and inform dredging activities. For instance, during maintenance of navigational channels. It is used as an echosounder attached to the survey board. They also analyze and define the tides, surroundings, currents, and shorelines to make a better model of the area features overall. HOW TO PERFORM A BATHYMETRIC SURVEY?

Equipment Inspections and Calibration In the survey area, mobilization of all equipment can involve transporting the survey boat and launching it. This is only transport of equipment which can then be used on a local hire boat as that can be more cost-effective in some cases. 2. Mobilize Each Equipment This contains the setting up of a bespoke frame which is applied to add all the equipment tightly to the boat. When the boat is moving to make sure high-quality data, this keeps it firmly in place. The transducer is involved in the underwater portion of this frame and the GNSS (GPS) transmitters are affixed at the top of the frame to have as great a view of the sky as potential. The “control hardware” – the echosounder and the GNSS controllers are then linked via marine cables to all additional equipment and the control computer. The software is then placed up with details about the survey noted in its records. 3. Deployment and Equipment System 4. Sound Casting Measurement of the speed of sound at a Width site to calibrate the transducer. This is because the speed differs with salinity and temperature it can considerably affect the reading of depth. Whilst monitoring the depth data over the whole area to be surveyed, this includes driving the boat. This is done by following subsequent lines. These lines will be very close together in narrow waters and where the accuracy needed is high. This is a fast look at overall data gathered to see whether any apparent areas require additional data collection. 5. Begin the Survey 6. Check the Data Before Demobilization Power down all equipment, detach, and clean with fresh water. 7. Demobilize Utilizing specialized software, the data must be handled with a powerful workstation computer. Any inaccurate data is eliminated, and the final map is created. 8. Process the Data Bathymetric surveys will be beneficial if all the steps are performed effectively. The above information can be helpful to know more about these steps. These steps will guide how to make surveys and how to use data collected through them. Contact #209, 2nd Floor - Apricot Tower P.O.
